Patented Aug. 11, 1931 UNHTE STATES VALENTIN IBIALAS, OF CHICAGO, ILLINOIS SPARK PLUG CLEANER Application filed June 25,

'The invention relates to spark plug cleaners and the object of the invention is to provide a container one end whereof is open and tapped, said container being adapted to re ceive a cleaning fluid such as gasoline, and adapted to have a spark plug screwed into the tapped end of said container.

A further object of the invention is to provide means inside the above mentioned con tainer adapted to be moved longitudinal of said container, and to impact against the portion a spark plug, which would be located inside of the container, when the spark plug is attached to said container.

Other objects of the invention not specifically mentioned may be easily ascertained and understood from the following description in connection with the accompanying drawings forming a part thereof. It is however to be noted, that the invention is not to be limited or restricted to the exact construction or formation shown in the drawings and described in the specification but that said invention is only to be limited by the scope of the claim appended hereto.

In the drawings illustrating a preferred embodiment of the apparatus forming the subject matter of this invention Fig. 1 is a side view of the apparatus for to cleaning spark plugs according to the present invention partly shown in section.

Fig. 2 is a longitudinal section of said apparatus showing a spark plug connected therewith and Fig. 3 is a sectional view taken on line 3-3 in Fig. 2.

Preferably the container has a cylindrical body 5, the lower end of which may be closed by means of a bottom 6. In the drawings this bottom is screwed into the body 5, but it is to be understood, that the bottom may be either an integral part of the body or may be fastened thereto in any suitable and convenient manner. Adjacent the other end the body 5 is tapped as indicated at 7, and a spark plug 8 may be held removably connected with the container formed by the body and the bottom by being screwed into the body. A cage is constructed in the following manner and for in a. purpose to be described later. The cage 1930. Serial No. 463,727.

consists of two perforated plates 9, each having the shape of a circular disc, on which a plurality of ears 10 are provided. Pins 11 are provided adjacent each of their ends with a shoulder and extend through holes provided for this purpose in the ears 10. The parts of the rods 11 extending through said holes are then riveted over so that the disc like plates will be held together, and at the same time will be spaced from each other by means of the shoulders on pins 11. Straight wire rods 12 are pointed at one of their ends as indicated at 13, and are flattened off at their other ends as indicated at 14;. The wire rods are inserted through the perforations in the discs .9, so that the pointed ends will be on top. A pair of circular grooves are provided 7 in the interiorof the body 5, at a distance from each other which is approximately equal to the height of the cage described above. A circular spring 15 is then arranged in the upper circular groove, and then the assembled cage with the wire rods in place is placed inside the body, whereupon a second circular spring 16 is inserted in the second groove, so 7 that the cage will be held in position between the two springs, which engage the outer part of the ears 10 as indicated in Fig. 3.

The assembling of the apparatus is preferably done from the bottom and for that reason it is preferred to provide a removable bottom 6. After the cage and the wire rods are in position, the bottom is attached to the body, and now a cleaning fluid such as gasoline or the like may be poured into the container, and then a spark plug may be screwed into the upper end of the container.

By shaking the container back and forth in longitudinal direction in relation to said container the cleaning fluid will be forced 0 against the anode and kathode of the spark plug cleaning the same, and at the same time the wire rods will be impinging against the spark plug loosening any particles of carbon or the like, adhering to the spark plug too tightly to be removed simply by the gasoline.

By supporting the cage in the manner described the wire rods are protected against the danger of being bent in case one or the other of said rods shall happen to get stuck somehow between the anode and kathode or on any other part of the spark plug. hen the spark plug will be rotated to be removed from the apparatus such wire rods as may be stuck on the spark plug would be bent out of shape, when the cage would be held rigidly inside the body, but being held only between the two springs the cage may be rotated with the spark plug, so that the wire rods will not be distorted.

In order to make it possible to carry the apparatus filled with gasoline and ready for use a lid 17 may be provided, which can be screwed tightly onto the apparatus as indicated in Fig. 1.

Having described my invention and how the same is to be performed, I claim as new and desire to secure by letters patent:

In a device of the class described a cylindrical body, a bottom on one end thereof forming a container with said body adapted to receive a cleaning fluid, means on the open end of the body for firmly but removably holding a spark plug, so that the anode and kathode extend into the body, a cage constructed of a pair of perforated discs, each disc having a plurality of cars extending radially of said disc, and held spaced from each other, by means of pins having, shoulders adjacent their ends, means for holding, said cage rotatably and removably inside the body, and a plurality of wire rods extending. through the perforations of said discs, and adapted to moved axially therein.

In witness whereof I atfix my signature.

VALENTIN BIALAs.
